Open total dislocation of a talus with extrusion (missing talus) is an extremely rare injury. We present a case of a 63-year-old male who sustained an open total lateral dislocation of the right talus with extrusion and without a concomitant fracture after a fall from a small height. Tibiocalcaneonavicular arthrodesis was performed. Arthrodesis failed, and due to painful and unstable ankle, rearthrodesis was performed two years later, successefully. Because of rarity of this kind of injury, hers importance for foot function, previously described various treatment options and absence of guidelines, herewith we propose, according to our experience and review of literature, the algorithm for the treatment of this rare injury.
